Upgrading typings from 0.x to 1.x. Where is /typings?

Question

Writing an Angular 2 app in TypeScript, I'm trying to follow the 5 Min Quickstart guide. Recently the npm typings package went from 0.x to 1.x. According to the official instructions, we are supposed to delete /typings when upgrading so that's what I did. After deleting that directory, I ran npm uninstall typings, then npm install typings. I now have typings 1.1.0 installed.

Here is my typings.json

{
  "globalDependencies": {
    "core-js": "registry:dt/core-js#0.0.0+20160317120654",
    "jasmine": "registry:dt/jasmine#2.2.0+20160505161446",
    "node": "registry:dt/node#4.0.0+20160509154515"
  }
}

Problem is, I expected the installation to create a new /typings and fill it with the new file structure. However, I still have no /typings. Trying to run typings install throws the error 'typings' is not a recognized command, program or batch file (I'm on Windows 7). What gives?

Why it's a problem: The typescript compiler throws a lot of "Cannot find name 'Promise'" (or 'Set' or 'Map') errors unless I reference the (now deleted) ///<reference path="../typings/main/ambient/es6-shim/es6-shim.d.ts"/>

typings install would not be recognized (probably because I don't have it installed globally). To create and fill /typings, I needed to execute npm run typings install. This created /typings/globals and filled it with the packages in my typings.json.

In order to deal with the "Cannot find name 'Promise'" errors, I then changed the reference path I had in my bootstrap file to

the old: ///<reference path="../typings/main/ambient/es6-shim/es6-shim.d.ts"/>

to the new: ///<reference path="../typings/globals/core-js/index.d.ts"/>

Given that Angular 2 replaced es6-shim with core-js in typings.json recently

I had this issue too a while back. To fix it I added ///<reference path="../../node_modules/angular2-in-memory-web-api/typings/browser.d.ts" /> this reference path to tsd.d.ts file. The path might be different depending on how your environment is set up. But if I remember right browser.d.ts had the references for those typings.

Here is a related issue pre-release candidate. Angular 2 can't find Promise,Map,Set and Iterator
